Hey!
Funny coincidence, I asked more or less the exact same question today, a couple of hours before you. I have since stumbled upon a thread regarding this issue (
http://archive.ambermd.org/202105/0103.html) saying
>Please edit your run_cmake script, and add the following flag:
>
> -DFORCE_INTERNAL_LIBS="fftw"
>
>Then re-run "run_cmake" and "make install".
This was related to Amber20 and not Amber22 though, and I haven't yet been able to test if it works
Best
Florian

Subject: [EXT] [AMBER] Amber22 CUDA compilation problem
Hi All
I am trying to compile Amber22 with CUDA support. I tried many version of CUDA and GCC but sooner or later compilation failed.
My current configuration is
Currently Loaded Modules:
1) cmake/3.25.3 3) bison-3.0.4-gcc-7.2.0-nl7vmez 5) cuda/11.4.1 7) boost/1.75.0
2) python-3.7.0-gcc-12.3.0-tvnfvfi 4) anaconda/3.6 6) gnu7/7.3.0 8) fftw-3.3.7-gcc-4.8.5-5igtfs5
And the compilation ends like this:
[ 14%] Building CXX object AmberTools/src/cew/CMakeFiles/libcew.dir/iface.cpp.o
[ 14%] Linking CXX shared library libcew.so
/usr/bin/ld: /usr/local/lib/libfftw3.a(apiplan.o): relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC

/usr/bin/ld: /usr/local/lib/libfftw3.a(alloc.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
Could you please help me with this or point where to search for more information?
